Seems straightforward enough: duplicate the layer a number of times and use valueAtTime expression linked to the (animated) original layer for the rotation property of the duplicate layers along with layer index to offset the time.

try taking a layer and rotating it they way you want, then add the echo effect. increase the number of echoes and change the echo operator to 'composite in back' or 'in front' depending on your animation, and see if that can work for you.

you can also adjust the echo time (the default is the duration of a single frame at 29.97fps), and making that value positive or negative determine if the echoes trial the layer or precede the layer.

you'd still need to have a copy of that layer rotate and stop at the final point, so the echo layer would reveal that final layer.
